hi there...because you have aa ''big'' experience in audio recording computing...i want to ask you before start what kind of major settings do i need for my pc,to work fast without clicks pops and other things...i mean from BIOS do i need to disabeled something?...i've lerned from opus to disabeled writing cache from the op drive(i did it works better)...take a look to my system...and tell me what should i do?

Always disable anything built onto the motherboard you are not using, for example...on board audio, onboard modem, onboard SATA, onboard RAID, parellel port, serial ports..etc etc etc
Other than that, it's ready to go and as Tore said, go through my tweak guide and you'll be good as gold(or close to! )
